Abstract

A method is described for producing a can end from metal with at least one opening tab to be pushed in towards the inside portion of the can end. The method of this invention comprises the steps of forming a bulge which is directed upwards, partial punching of the opening tab for leaving a hinged area, displacing of the opening tab in relation to the edge area of the aperture towards the inside of the can end, final reforming of the edge area of the aperture and/or opening tab into a final form, and, if applicable, also coining the edge area of the opening tab so that the edge area of the aperture covers the edge area of the outside of the can end in the form of a ring. During the complete reforming and, if applicable, the coining operation, the two edge areas are held at a mutual axial distance from each other. [US5074732A]
